Computer Science

Programming has been a part of my life since I was about 6 years old after learning about viruses and trying to understand how video games were made. From there on I got into game development and software, eventually working my way up to scripting, web development, and app development soon after. Over time, I have come to learn and utilize over 50 different programming languages, across all platforms and in various environments. Since then, I have developed numerous pieces of software and published many research papers in computer science, alongside a few textbooks and other educational materials.

I also currently teach all the computer science courses at Craig High School in Janesville, WI, including AP Computer Science Principles, AP Computer Science A, Data Structures/Algorithms (Java), Web Development, Game Design (Godot), and Computer Programming I/II (Python/Adv. Python and C#) — as well as a few various online college-level courses. I have also worked as a webmaster, researcher, and senior software engineer, and currently do freelance graphic, web, app, and software design under my business Zero Development, which also hosts my portfolio of programs, research, and designs.

While I have been drawing all my life, I started doing graphic design around the same time I started programming; I was around 6 years old when I found out about Adobe Photoshop and Illustrator (Back when it was only CS2!) and had obtained my own copies of the software. I watched tutorials nearly daily for months, trying to figure out the art styles of other digital artists. I eventually started doing basic logos and things such as forum signatures, back when that was actually popular (2007 - 2010). Since then, I have developed my graphical art style over the past few years, eventually developing an art form nearly identical to Google's Material Design about 2 years before its release and widespread. This art style was used to populate my YouTube channel at the time I was an early high school student, among taking up freelance art for others.

Since then, after the start of my freelance web/software/graphic design business, I have taken up commissioned art for companies in need of logos and websites, as well as mockups for such and software, including mobile apps.
